CARBURETOR.

Application led July 12, 1920. Serial No. 395,684.

To all fw 710m t may concern Be it known that we, RALPH F. PRoo'roR and WILLIAM R. Pnooron, citizens of the United States of America, residing at l/Vest Point, in the county of Clay and State of Mississippi, have invented new and useful Improvements in Carburetors, of which the following is a specication.

The object of the invention is to provide a construction and arrangement of parts whereby a reserve emergency carburetor may be employed under such conditions as to permit of the utilization of the same, without loss of time in the event that the main carburetor should fail for any reason to properly function, to the end that the loss of time incident to re-adjusting or re'A pairing the main carburetor may be avoided and also to provide means whereby the second or auxiliary carburetor may be uti4 lized or put into commission when the conditions of the motor or temperature are such as to make it desirable or necessary to utilize the heat of the exhaust from the engine to obtain the maximum benefit of the fuel, and with these objects in view7 the invention consists of the construction and combination of parts7 of which a preferred embodiment is shown in the accompanying drawings, wherein The figure is a sectional view of an apparatus providing for the alternative or interchangeable use of main and auxiliary carburetors.

The main and auxiliary carburetors are represented typically at 10 and 11 respectively in communication with the fuel feed pipe 12 and are disposed respectively in communication with the longitudinally aligned branches 13 and let respectively of the down leg of the intake manifold 15, these branches being formed adjacent said down leg with valve seats with which the piston valve 16 may engage, the stem 17 of the valve passing through a suitable guide at the extremity of the branch 13 for actuation at a remote point to seat the valve to close either one of the branches so as to leave the other in communication with the down leg and with the manifold. i

Preferably the auxiliary carburetor 11 is arranged in a jacket 1S communicating with a drum 19 through which extends a heat conductor 20 which may lead from the exhaust manifold of the engine to the end that the said auxiliary carburetor is maintained at a temperature facilitating the va.- porization of the fuel and the eficiency of the apparatus is maintained under conditions which ordinarily' would render the average carburetor ineffective.

bviously the arrangement indicated provides for the use of the ordinary carburetor in the ordinary way under normal conditions and yet permits of the connection of thev auxiliary or complemental carburetor with the intake manifold at a moments notice in the event of failure or temporary ineiiiciency of the main carburetor or in the event that by reason of an extremely low temperature or an insuiiicient supply of fuel is obtained through the usual means,-

the change being effected by simply shifty ing the control valve to close one or the other of the branches 13 or 14;.

The invention having been described, what is claimed as new and useful is The combination with an intake amant fold having a down-leg and longitudinally aligned branches extending in opposite directions therefromand formed with valve seats adjacent said down-leg, of main and auxiliary carburetors having communication respectively with said branches and having a common source of supply, a piston valve disposed for engagement with either of said seats to selectively place one or the other of the branches in communication with said down leg, and a valve stem extending axially through one of the branches to a remote point for actuation of said valve for the purpose specied.

In testimony whereof they aix their signatures.
